Given the mapping in the figure, the range set is:
{1, 2, 5, 5, 8}
{2, 5, 8}.
{2, 3, 5}
{1, 2, 3, 4}
The function f is defined as R, the set of real numbers by f:x → 3x -2,
What is f⁻¹: x → :
(x-3)/2.
(x+3)/2.
(x-2)/3.
(x+2)/3.
The figure shows a relation from set A to set B.
The range of the relation is:
{1, 2, 3, 4, 5}
{a, b, c, d}
{1, 2, 4}
{ (a,1), (b,1), (c,4), (d,2) }
The mapping represented in the figure is:
Many – 1.
1 – many.
Many – Many.
1 – 1.
Given the function f defined over R by f:x → 2x² - 3.
The value of f(-2) is:
-11
-5
5
-7
